After a misfired snap that ricocheted off offensive guard Bobbie Williams' leg for a botched extra point against the Cleveland Browns, long snapper Morgan Cox said he has to be mindful of every detail. "Yeah, it's my responsibility to make sure those guys are in place," Cox said. "I should have moved Bobbie's foot out of the way. It skimmed his leg. It was a simple miscalculation on my part. He doesn't know where his foot is supposed to be. If he's off, I've got to move his foot." Chiefs inside linebacker Johnson went to the Pro Bowl last season after recording a career-high 132 tackles with two interceptions and leads his team with 32 tackles this year. In a 2009 game against Baltimore, he returned an interception 70 yards. "You always have to know where he's at," running back Ray Rice said. "When he's playing at a high level, their defense plays at a high level." No Ravens players were fined for any plays against the Browns, according to an NFL spokesman.
